Vaccinivirus disease

Vaccinivirus disease, caused by the pathogen Vaccinivirus cadovaccinii, is a specific viral infection affecting the vascular system of various agricultural and ornamental crops. The pathogen belongs to a group of viruses capable of rapid systemic transmission within plant tissues, which significantly complicates early diagnosis and subsequent management of the disease.

The main crops most susceptible to this virus are members of the Solanaceae and Cucurbitaceae families. The infection is most frequently recorded in greenhouse operations and areas with intensive vegetable production, where high planting density facilitates the rapid spread of the pathogen through contact surfaces and horticultural tools.

The primary symptoms of infection include chlorosis of the leaf blade, the formation of a characteristic mosaic pattern, and general stunted growth of the plant. In the active phase of the disease, stem deformation and partial necrosis of growth points occur, leading to a critical decrease in crop yield and loss of fruit marketability.

The development of the disease is directly dependent on temperature conditions and the activity of insect vectors. Optimal conditions — high humidity and moderate temperatures between +20 and +25 degrees Celsius — create an ideal environment for the multiplication of viral particles and their active movement through the plant's phloem.

The harmfulness of Vaccinivirus cadovaccinii lies in the irreversible disruption of metabolic processes. Recommended protective measures include strict phytosanitary control, the use of virus-free planting material, and regular disinfection of agricultural equipment. If symptoms are detected, infected plants must be removed immediately from the field to prevent the spread of an epiphytotic.
